No I do not. I follow UL-96a and install/design per the standard. Then get an inspection for the master label.
I would be interested in viewing a pdf file of UL96a as well.
Thank you.

No I do not, just in text. Bought it years ago when I was doing installations.

doc is based on 96A. I have done some work there. From what I found you can buy it from UL... >$500 Try your local library or science library at your local university. John Luke Perrier (spelling?), worked for ETI he does seminars on lightning protection. He did his masters and I believe PhD in lightning protection. Check with your local ETI office to see if he is still doing these. He is really good at explaining the concepts.
